Hi, my name is Chris Wade, and I'm a contractor for the city of Los Angeles and today I'm going to show you how to remove and re-grout. We're here at our mock-up station, workstation here and I'm going to show you how to, we're going to remove the grout and we're going to replace it. There's several reasons why we would do that. The grout is old, it's brittle, it's coming out, it's stained. There's a whole number of reason for doing it. I'm going to use a dremel tool because that is the easiest way to go about it. You can use this sort of a thing, get in there, there's other tools that are available used by hand. There's scraping, pulling but quite honestly if you're going to do a whole area, you're going to want to use a dremel tool. It's a small little disc on here and it is going to create dust so there's a couple different ways you can deal with that. You could use a sponge dipped in water and as you're coming across here just squeeze it and just keep the dust down but it's a good idea to wear a mask, possibly some glasses or even have a fan in there but for viewing purposes we're just going to jump right in and do it. Here we go. You just want to take it across, watch out for the tiles. You want to go down as far as you can get down in there. You don't have to go all the way to the thinset. You just want to be able to get enough out that when you replace it it does dry and adheres to each other. You just want to run it across. You want to keep working it back and forth until you get all the tile out, get all the grout out of there. Once you're done doing that, you take your brush and you just want to get it and clean it all up. Sometimes you'll have to take your scraper here and just kind of finish it off on the areas, brush it out, get all that loose debris out of there. Then, we're going take our already mixed grout and you want to take a plastic knife, make sure you use a plastic knife do not use a metal one or you will scratch your tile, just get it in there, scrape up as much as you can. Then we're going to take our sponge, take our sponge, dip it in water, wring it out real good and just start wiping up all the excess. It's a good idea just to do it a few times. Otherwise it will start building back up on the tile, dip, don't hit it too hard otherwise it will start pulling out what you just put in, just basically we're trying to wipe it off the tile. And that's how you remove grout and replace it, nothing to it.
